I play an undocumented game, which is also included in XP. It is called 'Avoid the Blue Screen Of Death', it is very addicting. The aim of the game is to keep your computer in up to date shape, latest drivers, service packs, fixes etc. With the latest addon, 'Are you afraid of the .Net Framework?' you mustavoid bad programmed .Net software and keep an eye on all the private things on your computer. I must say, it is the most realistic game I ever played.
